Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for opening and closing a window of a vehicle, and more particularly to a control system for opening and closing the window from outside the vehicle while the engine is stopped.

[0002]

2. Description of the Related Art A control device has been proposed in which a window opening / closing motor is driven by inserting a key into a key cylinder of a door and rotating the door to open / close the window from the outside of the vehicle (Actual No. 54-89723). Gazette).

[0003]

In the control device, all windows of the vehicle are controlled to be opened and closed at the same time. However, not all windows reach a predetermined open position or closed position at the same time. Therefore, even if a so-called lock current is flowing to the window opening / closing motor related to the window that has already reached the predetermined position, electric power is supplied until all the windows reach the predetermined position. However, the lock current is
Although the current is several tens of times higher than the current required for normal operation, the engine is not driven, so the battery load is large and the voltage drops considerably. As a result, it may not be possible to open and close the window, and eventually start the engine.

An object of the present invention is to provide a vehicle window opening / closing control device capable of reducing the load on the battery while the engine is not driven.

[0005]

SUMMARY OF THE INVENTION The present invention is a device for controlling the opening and closing of a plurality of windows of a vehicle, the key lock outputting an opening signal or a closing signal by rotating a key cylinder provided on a door. A switch, a window driving means for independently opening and closing each of the plurality of windows, and a control means for receiving the opening signal or the closing signal are provided, and the control means is provided with a predetermined signal after the opening signal or the closing signal is input. When the time has elapsed, the plurality of window drive means are sequentially operated, and the operation of the window drive means relating to the window that has reached a predetermined position among the plurality of windows is stopped.

In a preferred mode, the control means operates a window drive means to be followed when a predetermined time has elapsed after the operation of the preceding window drive means or when the operation of the preceding window drive means is stopped. .

In another preferred embodiment, the control means is
When at least one window driving means is operating to close the window, immediately after the opening signal is input from the key lock switch, the at least one window driving means is operated to open the window for a predetermined time.

[0008]

When the opening signal or the closing signal is input from the key lock switch, the control means sequentially operates the plurality of window driving means after a predetermined time has elapsed. Then, the operation of the window driving means relating to the window reaching the predetermined position is stopped.

Since a plurality of window drive means are sequentially operated and the operation of the window drive means relating to the window which has reached a predetermined position is stopped, no lock current flows. This reduces the load on the battery and reduces the voltage drop.

The control means operates the plurality of window driving means after a predetermined time has elapsed after the opening signal or the closing signal was input. This makes it unnecessary to provide the key cylinder with a rotation operation range exceeding the lock and unlock rotation ranges as described in the above publication, and enables the use of a conventional key cylinder with a key lock switch. To do.

According to a preferred embodiment, the window driving means to be followed is operated after a predetermined time has passed after the operation of the preceding window driving means or after the operation of the preceding window driving means is stopped. The time during which a plurality of window driving means operate in parallel can be reduced or eliminated. Thereby, loss due to Joule heat can be suppressed.

According to another preferred mode, when the hand is put on the window which is being closed, the window can be opened immediately by switching the key lock switch to the open position.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS.
The key lock switch 14 controls the opening and closing of 2
And a window drive means 16 and a control means 18.

The key lock switch 14 outputs a closing signal when the key cylinder 22 provided on the door 20 of the driver's seat is rotated to the lock position A, and the unlock position B is output.
The opening signal is output by the turning operation to. In the embodiment shown in FIG. 8, a ring illuminator 24 is arranged around the key cylinder 22. The ring illuminator 24 is known per se and blinks, for example, in a cycle of 1 second.

The window drive means 16 is composed of a power window motor and independently opens and closes each of the windows 12. Usually, a passenger car as shown comprises four windows 12. Therefore, there are four window driving means 16 in total.

In the illustrated embodiment, the control means 18 includes a timer circuit 30 for controlling the delay time and the operating time, a drive circuit 32 for operating the window drive means 16, and whether or not the window drive means 16 is stopped. And a lock current detection circuit 34 for detecting the lock current, which is connected to the battery 36 and the key lock switch 14, respectively. The timer circuit 30 includes a control circuit that selects the window driving means 16 to be activated based on the signals from the key lock switch 14 and the lock current detecting circuit 34 and specifies the window driving means 16 that has stopped operating. I'm out. When the open signal or the close signal from the key lock switch 14 is input to the control means 18, the control means 18 performs the control described below.

When the key is inserted into the key cylinder 22 and is rotated to the lock position A or the unlock position B, the door is locked or unlocked, and at the same time, the key lock switch 14 is closed or opened. Is turned on. The door lock or unlock operation is completed in about 1.5 seconds, for example. Therefore, FIG.
As shown in, the ON time t ₁ of the key lock switch 14
When it is less than 1.5 seconds, the window drive means is not activated. Note that FIG. 2 is an example of control in which all windows are fully closed or fully closed when all windows are fully open or fully closed.

When the key lock switch is turned on, timing of T ₁ and delay time t ₂ is started. When the delay time t ₂ reaches 1.5 seconds, for example, the window driving means of the driver seat D, which is the driver's seat, is activated at T ₂ , and at the same time, the timing of the delay time t ₃ is started.
If the delay time t ₃ becomes 3 seconds, for example, T ₃ , and if the window driving means for the D seat is in operation, the window driving means for the front seat P, for example, is not waited for until it stops. Operate. After that, when the operation of the window drive means of the D seat is stopped T ₄ , for example, when the operation of the window drive means of the rear left seat RL seat is operated and the operation of the window drive means of the P seat is stopped T ₅ , for example, , Rear right seat RR

On the other hand, the ring illuminator flashes from T ₂ when the window driving means of the D seat is activated to T ₇ when the window driving means of the RR seat is deactivated to indicate that the window is open or closed.

According to the embodiment shown in FIG. 2, the delay time t ₃
Even when the preceding window drive means is in operation when the time elapses, the window drive means to be followed is operating, so that the operation time for opening and closing the window can be shortened. On the contrary, if the operation of the window drive means of the D seat is stopped before the delay time t ₃ elapses, the operation of the window drive means of the P seat should be started from the stop of the operation of the window drive means of the D seat. Operation time can be shortened.

FIG. 3 shows an example of control when the key lock switch is temporarily turned off during operation of the window drive means.

When the key lock switch is turned on, time T ₁₁ and measurement of delay time t ₂ are started. When the delay time t ₂ reaches 1.5 seconds T ₁₂ , the window drive means of the D seat is activated, and at the same time,

The window drive means of the P seat is operated without waiting for the stop. After that, when the operation of the window driving means of the D seat is stopped, at T ₁₄ , the window driving means of the RL seat is operated. If the key lock switch is turned off while the window drive means is operating, then the P seats and RL that are operating at T ₁₅ at that time.
The operation of the window drive means of the seat is stopped.

After the lapse of the OFF time t ₄ , when the key lock switch is turned ON again, the time T ₁₆ and the delay time t ₂ are counted. Then, when the delay time t ₂ reaches 1.5 seconds, at T ₁₇ , the window driving means of the D seat is operated. At this time, since the window opened or closed by the window driving means of the D seat has reached the predetermined position, a short time T ₁₇ -T ₁₈
Only the lock current flows. When the lock current disappears T ₁₈ ,
The window driving means of the P seat is operated, but since the window of the P seat has already been opened or closed, when a short time for opening or closing the intermediate stop position to the predetermined position has elapsed T ₁₉ , its operation. Then, the window driving means of the RL seat is operated. At the same time, and starts counting the delay time t _3, actuating the the window driving means T _20, RR seat when the delay time t ₃ becomes 3 seconds. Since the window driving means of the RL seat has already been opened or closed, the window drive means has a short time for opening or closing the window from the intermediate stop position to the predetermined position. When the short time elapses, the window driving means of the RL seat at T ₂₁ and at the time T ₂₂ are deactivated so that all the windows reach the predetermined positions. On the other hand, the ring illuminator blinks while the window driving means is substantially operating to indicate that the window is open or closed.

FIG. 4 shows an example of an emergency control for opening the window which is being closed when the window is being operated to be closed.

Activate the window drive means of D seat, and at the same time, delay time
Start timing of t ₃ . When the delay time t ₃ becomes 3 seconds T ₂₃ ,
If the window driving means for the D seat is operating, the window driving means for the P seat is operated without waiting for the stop. In this case, it is assumed that the window for seat P is at the intermediate position. Therefore, when a small amount of time has passed, at T ₂₄ , the window driving means relating to the window of the P seat stops operating due to the lock signal. By stopping the operation of the window drive means of the P seat, the window drive means of the RL seat is operated,
After that, when the operation of the window drive means of the D seat is stopped

When the window for the RL seat and the window for the RR seat have reached the substantially closed position T ₂₆ , the key lock switch is turned off, and after a short time T ₂₆ -T ₂₇ , the key lock switch is switched to the unlock side. As a result, RL seats and R
The window driving means of the R seat is operated to open the window for a predetermined time t ₅ . The predetermined time t _5, for example, to 1 second. When the predetermined time t ₅ has passed, at T ₂₈ , the window driving means of the RL seat and the RR seat is stopped.

The key lock switch is switched to the lock side again after a short time T ₂₉ -T ₃₀ has elapsed. Starts counting the time T ₃₀ delay time t _2, actuating the the window driving means T _31, D-seat when the delay time t ₂ becomes 1.5 seconds. At this time, the window closed by the window driving means of the D seat has reached the predetermined position, so that the short time T
_The lock current flows only for ₃₁ -T ₃₂ . When the lock current is exhausted T ₃₂ , the window driving means of the P seat is activated, but at this time, the window closed by the window driving means of the P seat has reached the predetermined position, so a short time T ₃₂ -T Only ₃₃ lock current flows. When the lock current is exhausted T ₃₃ , the window driving means of the RL seat is activated. At the same time, and starts counting the delay time t _3, actuating the the window driving means T _34, RR seat when the delay time t ₃ becomes 3 seconds.
Then, the RL seat T ₃₅ time, and stops the operation of the window driving unit RR seat when T _36, to reach all the window to a predetermined closed position. On the other hand, the ring illuminator blinks while the window driving means is substantially operating to indicate that the window is open or closed.

The above control example can be implemented by the control circuits shown in FIGS. Note that, in FIGS. 5 and 6, what is described before the electronic element schematically shows the state of the signal input to the electronic element in relation to the current or voltage for generating the signal. .

When the key lock switch is turned on, all RS flip-flops (hereinafter referred to as FF) 50, 6
6, 68, 78, 80, 90 and 92 are reset. When the key lock switch is turned on, the L signal enters the inverter 52 and the H signal from the inverter 52 enters the AND gate 54. On the other hand, from turning off the key lock switch
Although the fall from H to L occurs due to the switching to ON, the delay time t ₂ starts counting from the fall. After the delay time t ₂ , the H signal is input to the AND gate 54, and as a result, the AND gate 54 outputs the H signal to the H gate.
The signal is output. At this time, since the output of the inverted Q of the FF 50 is H, the H signal is output from the AND gate 56,

As a result, the output of the inverted Q of the FF 50 becomes L, and the L signal is output from the AND gate 56. As a result, the operation of the window drive means of the D seat becomes the stopped state 60.

When the H signal is output from the AND gate 56, timing of the delay time t ₃ is started by the rise of the signal. After the delay time t ₃ , the H signal changes to the OR gate 6
After 2 the AND gate 64 is entered. On the other hand, the pulse generated by the fall of the output of the inverted Q of the FF 50 from H to L causes the FF 66 which has been in the reset state to be in the set state and the Q output to be in the H state. This H signal is O
The AND gate 64 is entered through the R gate 62. On the other hand, A
Since the FF 68 connected to the ND gate 64 is in the reset state, the output of its inversion Q is H. As a result, the H signal is output from the AND gate 64, and the window driving means of the P seat is in the operating state 70. In this case, OR
Since the output generated when the delay time t ₃ has elapsed and the output that passes through the FF 66 when the lock current of the window driving means of the D seat is detected are input to the gate 62, the window driving means of the P seat is It will be activated by the signal that occurs earlier.

It becomes 2.

When the H signal is output from the AND gate 64, the delay time t ₃ is started by the rising of the signal. After the delay time t ₃ , the H signal enters the AND gate 76 via the OR gate 74. On the other hand, the pulse generated by the fall of the inverted Q output of the FF 68 from H to L causes the FF 78 which has been in the reset state to be in the set state and the Q output to be in the H state. This H signal is
The AND gate 76 is entered through the OR gate 74. on the other hand,
Since the FF 80 connected to the AND gate 76 is in the reset state, the output of its inversion Q is H. As a result, the H signal is output from the AND gate 76, and the window driving means of the RL seat becomes the operating state 82. In this case, O
Since the output generated when the delay time t ₃ has elapsed and the output that has passed through the FF 78 when the lock current of the window driving means of the P seat is detected are input to the R gate 74, the window driving means of the RL seat is It will be activated by the signal that occurs earlier.

When the lock current detection circuit in the RL seat detects the lock current, a rise from L to H occurs, and the FF 80 is set by the pulse generated by the rise. As a result, the inverted Q output of FF80 is L
And the L signal is output from the AND gate 76. As a result, the operation of the window driving means of the RL seat is brought into the stopped state 84.

When the H signal is output from the AND gate 76, the rising time of the H signal starts the measurement of the delay time t ₃ . After the delay time t ₃ , the H signal becomes the OR gate 8
After 6 the AND gate 88 is entered. On the other hand, the pulse generated by the fall of the output of the inverted Q of the FF 80 from H to L causes the FF 90, which has been in the reset state, to be in the set state and the Q output to be H. This H signal is O
The AND gate 88 is entered through the R gate 86. On the other hand, A
Since the FF 92 connected to the ND gate 88 is in the reset state, the output of its inverted Q is H. As a result, the H signal is output from the AND gate 88, and the window driving means of the RR seat becomes the operating state 94. In this case, O
Since the output generated when the delay time t ₃ has elapsed and the output that passes through the FF 90 when the lock current of the window driving means of the RL seat is detected are input to the R gate 86, the window driving means of the RR seat is It will be activated by the signal that occurs earlier.

When the lock current detection circuit in the RR seat detects the lock current, a rise from L to H occurs, and the FF 92 is set by the pulse generated by the rise. As a result, the inverted Q output of FF92 is L
And the L signal is output from the AND gate 88. As a result, the operation of the window drive means of the RR seat is stopped 96.

When the window is about to be closed, emergency opening control is performed as shown in FIG.

When the key lock switch that is ON on the lock side is turned OFF, a rise from L to H occurs,
A pulse is generated for a short time t ₆ , and the H signal enters the AND gate 100. On the other hand, when the key lock switch is switched to the unlock side and turned on, a fall from H to L occurs, a pulse is generated for a short time t ₆ , and the H signal is ANDed.
Enter gate 100. The short time t ₆ is the time T in FIG.
Equivalent to ₂₆ -T ₂₇ , for example 0.5 seconds. When the output of the AND gate 100 rises to H, a pulse having an interval of a predetermined time t ₅ is generated and the AND gate 102 is entered. On the other hand, in the window drive means that has been operating until just before the key lock switch is switched, the key lock switch is turned off, causing a fall from H to L. A pulse having an interval of time t ₅ generated by this rising enters the AND gate 102, and puts the window driving means, which has been operating until just before the key lock switch is switched, into the state 104 which is opened for the time t ₅ . At this time, the ring illumination 110 is blinked by the H signal output through the OR gate 106 and the OR gate 108.

Since the window driving means relating to the window which has already reached the predetermined position which has been closed immediately before the key lock switch is switched, or the window which has not been operated yet, is in the L state immediately before the key lock switch is switched. , Not affected by the control. On the other hand, the window drive means that has been operating until just before the key lock switch is switched stops after the predetermined time t ₅ . After that, when the key lock switch is switched to the lock side and turned on, the control shown in FIG. 5 is performed.
